This is dated December 1994. It feels like a test level. You face 32 mostly weak monsters in a series of square corridors and rooms, each of which has a different texture. There's one elevator, one crushing ceiling, one trap, one rising stairwell etc, as if the author was trying each one out. At the end there are two identical "mazes" made out of doors. It features several unmarked secrets you would only find if you pressed every single wall in the map.
